Diseño y construcción de un prototipo para la obtención de polvo metalico a partir de la viruta generada de los procesos de mecanizado del CIRT unidad de negocios Hidroagoyan.

Abstract

In the technological proposal presented, the design and construction of the prototype were carried out to obtain metallic powder from the chip generated from the machining process, For which it was necessary the bibliographic analysis and study of the techniques of obtaining a powder, the most convenient alternative is selected to achieve this objective through the use of the QFD matrix and the weighted criteria method, the planetary ball mill. Then it proceeded to the mechanical design and selection of each element that makes up the prototype, using simulation tools: SOLIDWORKS, ANSYS, ADAMS and SAP2000. Subsequently, the plans of the elements were developed through the elaboration of processes flowcharts, the construction and assembly of the prototype were carried out. The functional tests were performance tests with bronze, transmission steel and Steel ASTM A743, at a maximum supply capacity of 220 gr and a speed of 400 RPM for two, four and five hours, with 25 tempered steel balls of 20 mm during the first and second grinding hours, used in the remaining time 100 of φ10 mm. Afterward the powder was sieved having 153 gr of bronze between 0,6 to 0,06 mm and 69 gr ≤ to 0,06 mm of where the 57 , 14% is in a range of 2.49 to 9.74 μm, in the transmission there is 143 gr between 0.4 to 0.06 mm and 76 gr below these limits with 58.57% between 1, 02 to 4.72 μm, in the stainless 129 gr have from 1 to 0.06 mm where 86 g are smaller with 78.57% between 2.13 to 8.45 μm, it is concluded that if it is possible to obtain stainless steel metallic powder especially. It is suggested to follow the recommendations presented in order to expand this investigation.
